Last season: Once again the Bulls outworked everybody in the regular season — while 29 teams treat games like the regular season, the Bulls grind every night and they were a league best 50-16 because of it. And that was with Derrick Rose missing 27 games. They were the top seed in the East and we were finally going to get an answer to the question if they could raise their game and challenge the Heat in the playoffs.

Except, we didn’t get that answer because Rose blew out his ACL on a jump stop at the end of the first playoff game. (And no, it wasn’t his shoes, stop that nonsense.) With Rose out the Bulls dropped four of the next five to the Sixers and were bounced in the first round.

Key Departures: The Bulls front office decided to shake up the bench — over the objections of coach Tom Thibodeau who thought that bench was key to Chicago’s 18-9 when Rose was out last season.

Key Additions:Marco Belinelli comes in as the new Kyle Korver, and that could well be an upgrade. Belinelli can shoot the three but also has a pretty well rounded game when healthy. Also added to the list are Kirk Hinrich, Nazr Mohammed, Vladimir Radmanovic and Nate Robinson. Hinrich will provide some solid play (although he’s not a great point guard, he’s better as a spot up guy), but Bulls fans shouldn’t expect too much out of the last three. Not consistently, anyway. Robinson will have his nights.

The Bulls also drafted Marquis Teague out of Kentucky, with hopes of grooming him to be Rose’s backup.

Three keys to the Bulls season:

1) When does Derrick Rose return, what does he play like when he does? For all the talk about what to make of Carlos Boozer, or how good Luol Deng and Taj Gibson can be, the Bulls are still Derrick Rose’s team. Those other guys can be key components, but Rose is the superstar you build around. Without him they are not the same, particularly on offense. The Bulls were fine in the regular season thanks to their work ethic and defense, but when they ran into a focused and (with Rose gone) simply better Sixers team they were done quickly.

Reports have Rose returning somewhere around March, maybe a little earlier. The good news is owner Jerry Reinsdorf, having long regretted allowing Michael Jordan to return too quickly from an injury, is not going to make that same mistake with Rose. The Bulls star will be fully cleared by doctors before he steps on the court. Which is the right play — this is your franchise anchor for the next decade. Think long term, not short.

When he does come back, he might not quite be his old self. Not at first. There will certainly be rust on his game but the bigger issue with guys coming back from ACL tears is them fully trusting their reconstructed knee again. Rose was the league’s most explosive player, he had a jump stop and quick changes of direction that dazzled. It may be a while before he makes those moves with the same force again. Like maybe during the 2013-14 season.

2) Where are the points going to come from? Luol Deng and Taj Gibson are fantastic defenders and paired with Joakim Noah and Thibodeau’s drive you can bet the Bulls will remain one of the best defensive teams in the NBA.

But Rose was the offense — not just his points, he was the catalyst for everyone else. No one player can make that up and the Bulls will try to do it by committee, but they will be a much easier team to defend now. Deng and Gibson both took nice, efficient steps forward on offense last season and they need to make leaps this season again. Deng played through last season (and the Olympics) with ligament issues in his wrist, he needs to do it again and play like it wasn’t even an issue. He needs to keep draining threes. As for Richard Hamilton, he slowed down last season as he didn’t get to the line as often — he doesn’t create his own shots any more. He is not going to pick up a lot of the slack.

Bulls’ fans saying “this is why we pay Carlos Boozer” should know you pay him to be the No. 2 guy. He is an All-Star level regular season scorer and rebounder (15 points, 8 rebounds a game last year and he is efficient in the lane), and he will continue to make plays this season. He will score for you. But if you expect him to be a No. 1 guy you will be disappointed. He is what he is, what he has been since Utah. Jazz fans expected differently, too, and had the same feelings you do. My advice: Accept him for what he is and stop trying to make him into something he is not.

3) How big a drop off will there be from last year’s role players/bench to this one? You can try to argue — as some Bulls fans have — that the drop off from last season to this with the bench is not that severe. And it’s not as severe as some have suggested, but it is a drop off. Hinrich is not quite the same player that was with the Bulls last go around and has not looked strong at the point the last couple years, where Watson gave the Bulls quality play when Rose was out.

Nate Robinson will win the Bulls a couple games with instant offense off the bench, he will lose them a couple too by shooting them right out of it when he is cold. Nazr Mohammed will provide some points but his defense will drive Thibodeau crazy. Vladimir Radmanovic can play a limited role any more.

The bottom line is I wouldn’t trust this bench like the Bulls did theirs last season

What Bulls fans should fear: Jerry Reinsdorf’s penny-pinching ways. There are two areas it could come back to bite them.

One is the Thibodeau contract negotiations. The team and coach are talking about an extension, but it is possible that Thibs holds out thinking he is being lowballed and if he ever ends up on the open market he will have plenty of suitors. It’s not going to come to that. Thibs wants to stay and eventually I bet a deal gets done. The only thing that can hold it up is an owner lowballing one of the league’s best coaches. (Now, if you want to go with a shorter deal, say three years, I can see that because hard-a** coaches like Thibs can wear on teams.)

The other area is the roster retooling that is coming. The Bulls clearly have looked at the Heat, looked at their roster and decided they need another “A” list guy to go with Rose. I can see that. But you can’t just have Rose and Player To Be Named Later, you still need Deng and Gibson and Noah to make it all work. And that means paying some tax — which the Bulls are doing for the first time ever this next season, but do you want to bet on it as a trend?

How it likely works out: Make no mistake, the Bulls are going to keep defending, keep outworking every team they play up until Rose’s return, and then after. That is what they do. And with that they have some talent, they are going to get wins. However, they sacrificed depth and points are going to be a lot harder for them to come by this season. They will get wins, but the 18-9 record they had without Rose last year seems optimistic.

When Rose does come back, and as he finds his legs closer to the playoffs, they become the team nobody wants in the first round. With Rose they have a puncher’s chance against anyone.

Prediction: 45-37 in the regular season, which will net them a seven or eight seed. But once in the playoffs and with Rose back and feeling healthier, this is not the team any of the top seeds want to see in the first round. The Bulls may not get past them this year, but they will not be an easy out by any means.

Everybody is giving this team too much credit. Asik may be overpaid in Houston but he was a beast off the bench defensively. The Bulls bench is going to be terrible this year and Rose won’t be there to save them. If the Bulls go 40-42 and nab an 8-seed I would vote Thibs unanimously for coach of the year.

oh yeah this team will get themselves high draft pick this year sorry Chi town fans. i just don’t see this team cracking the top 8 teams, of course i could be wrong, but TOR. WASH. CLEV.will make a lot of noise this year not to mention MIL. being in the mix. Thibbs is a good coach, if he gets this team in the final 8 he will be in my mind a great coach

Last years team without Rose was no match for Philly in the playoffs. Now they get worse on the bench, and Philly improves with Bynum and you have Chicago winning 2 less games than Philly. Where’s that logic?

Correction: Last years team without Rose AND Noah wasn’t as good as the Sixers. Barely. Philly lost their best defender and best scorer, so I think they went sideways a bit. Good move for them I think, but I think it”ll pay dividends further down the road, not next year.

Barely? The Series was 4-1 Philly without Rose and I don’t remember which games Noah played and didn’t play, honestly. We did lose our best defender, but Evan Turner will now move into that spot, with the potential to do even better things than Iguodala (not necessarily defensive). Losing Lou will hurt, but we added Nick Young, Jason Richardson, and Dorell Wright for scoring. I think that more than makes up for that loss, not to mention Bynum. We were a top three defensive team last year with Spencer Hawes guarding the paint. Now we have one of the most dominant presences down there, who is a beast on the boards and is a very good shot blocker. There are also very few players that can guard him in the NBA. This is a much deeper Sixers team and a much thinner bulls team. You guys won games because of guys like CJ watson, Ronnie Brewer, Kyle Korver, Omar Asik. All of them are gone. This team is not two games worse than Philly.
